What You'll Receive
Full Description
Your customers expect instant, accurate answers at any hour. A custom AI chatbot delivers exactly that — reducing support load, qualifying leads automatically, and keeping visitors engaged around the clock. Zinn Digital, based in London, builds bespoke AI-powered chatbots trained on your own data and seamlessly integrated wherever your customers already are.
Whether you need a simple FAQ bot to handle your most common queries, a document Q&A assistant that reads your knowledge base and replies with precision, or a fully conversational customer support agent, this service covers it. Every chatbot is built on proven AI foundations — including GPT-based models, LangChain pipelines, and custom LLM training — so the responses are relevant, on-brand, and genuinely useful.
**What is included:**
- A custom AI chatbot trained on your specific dataset or requirements
- Choice of chatbot type: FAQ bot, article recommendation bot, document question-answering, lead generation, customer support, conversational, travel, real estate, restaurant, e-commerce, medical, dealer, business, or social media chatbot
- Integration into your chosen platform: website, mobile application, desktop application, WhatsApp Messenger, or Facebook Messenger
- Custom GPT integration (trained via GPT Builder where appropriate)
- An initial video call to fully understand your goals, brand voice, hosting setup, domain configuration, and OpenAI account requirements before a single line of code is written
**How it works:**
After you place your order, the team will schedule a Zoom call to walk through your objectives in detail — what the bot should know, how it should respond, and where it needs to live. Once requirements are confirmed and any necessary hosting or API access is in place, development begins. You will receive the finished integration within the agreed delivery window, with revisions available to refine responses and behaviour until you are satisfied.
**Who this is for:**
Business owners who want to reduce repetitive support tickets. Marketing teams looking to capture and qualify leads automatically. SaaS founders who need a conversational interface inside their product. Service businesses — estate agents, restaurants, clinics, travel companies, retailers — who want customers to get answers immediately without waiting for a human.
**Why Zinn Digital:**
Based in London with over two years of hands-on experience building AI chatbots and integrations across a diverse range of industries, the team brings both technical depth and a practical focus on outcomes. The process starts with a proper discovery call — not a generic template — so the chatbot actually reflects your business. Every project is treated as a collaboration, not a transaction.
Please send a message to discuss your requirements before placing an order, so the team can confirm scope and recommend the right package for your needs.

Frequently Asked Questions
Yes — it is strongly recommended. Every chatbot project is different, and a quick conversation beforehand ensures the right package is selected, scope is clearly defined, and nothing is missed. Please send a message with a brief outline of your requirements before purchasing.
A Zoom call will be scheduled so the team can fully understand your goals — what the chatbot should know, how it should behave, your preferred tone, and any technical requirements around hosting, domain, and OpenAI API access. Development begins once everything is confirmed.
You will need to share details about your business, the chatbot's purpose, any existing documentation or FAQs you want it to draw from, and access credentials for your platform or hosting environment if applicable. The team will guide you through exactly what is needed on the discovery call.
The chatbot can be integrated into websites, mobile applications, desktop applications, WhatsApp Messenger, and Facebook Messenger. If you have a specific platform in mind, mention it when you get in touch so compatibility can be confirmed.
Depending on your requirements, the chatbot may be built using GPT-based models (including Custom GPT Builder), LangChain pipelines, or custom LLM training. The most appropriate approach is selected based on your use case during the discovery call.
A revision covers adjustments to the chatbot's responses, conversational flow, training data, or integration behaviour based on your feedback. Each revision round is an opportunity to refine how the bot performs until you are satisfied within the revision allowance of your package.
Yes. Document question-answering chatbots can be trained on your own files, FAQs, articles, or knowledge base content so that responses are drawn directly from your material rather than general AI knowledge.
The service covers a wide range of sectors including real estate, restaurants, travel, e-commerce, healthcare, finance, customer service, lead generation, and general business use. If your industry is not listed, please get in touch — most requirements can be accommodated.
